Like other AMD family names, 10h ("10 hexadecimal") is a mostly-arbitrary, somewhat-sequential (new processor families receive unused higher family numbers) number, returned by the x86 <code>CPUID</code> instruction as a "Family number", and commonly written in hexadecimal. 10 in hexadecimal corresponds to the number 16 in decimal, meaning that while "Family 16" would also be a valid, if confusing, name for these CPUs, "Family 10" could also refer to the (apparently nonexistent) fam0Ah.

Family 10h (also known as fam10h, or ambiguously as fam10) is a family of AMD microprocessors corresponding to the K10 microarchitecture.

Like other AMD family names, 10h ("10 hexadecimal") is a mostly-arbitrary, somewhat-sequential (new processor families receive unused higher family numbers) number, returned by the x86 CPUID instruction as a "Family number", and commonly written in hexadecimal. 10 in hexadecimal corresponds to the number 16 in decimal, meaning that while "Family 16" would also be a valid, if confusing, name for these CPUs, "Family 10" could also refer to the (apparently nonexistent) fam0Ah.

Microcode

10h is the last CPUs with readable unencrypted microcode.
